Overview:

If you own a Yamaha with a 650 or 701 engine, this Enhancer is a necessity! The Enhancer produces a powerful spark with increased spark duration. Not only does the improved spark energy boost power, but this Enhancer features a more aggressive timing curve for even more power to get you going! At lower rpm you'll notice incredible acceleration and throttle response due to advancing the timing. Then as the rpm increases, the timing is retarded to the factory setting to prevent detonation and engine damage. For racers, there is also a lower rpm limit that you can activate for quick and consistent holeshots. By activating a switch mounted on the handlebar the rpm will limit at approximately 3,000 rpm. The instant the button is released, the rpm revs up just as normal and you rocket off. Everything you need to install the Yamaha Enhancer is supplied along with factory connectors for a direct plug-in installation!

    The book is so not fun to read
    Format: Paperback
    Nothing with the seller, it's just the book that I don't like. Black and white, full of info and boring

    It HAS helped with my energy levels!
    Size: 360 Count (Pack of 1)
    Might be better to take the powder, because I end up taking 12 of these tablets at a time to get the 6 grams of spirulina I want to take. But because they are simpler and cleaner than a powder would be, I may just stick with this! I have noticed my body has more stable energy on the days I remember to take this. And I can take them on an empty stomach which tells me they don’t have toxins or bad preservatives.

    Quality Spirulina, A "Superfood"
    Size: 360 Count (Pack of 1)
    Google Spirulina if you don't know what it is. In short, it's from algae (in this case) that has been shown to provide many health benefits, and studies are underway to validate other claims. One important value: it is one of the few foods that cover essential amino acids. As I said, do your own research. I'm relating what I read and my personal experience. This is, so far, the best spirulina I've found. It is a raw product, vegan, certified organic (by USDA), and proven "bio-active," meaning for me, I absorb it well. It does have an "algae taste" and mild odor (of same). This is difficult to describe, but call it a mild "hay" tone to the flavor. Since it's a pill, it shouldn't bother you. I did notice it the first few weeks, though. IMPORTANT: Not recommended for anyone suffering from phenylketonuria. Ask a medical professional first.
